JS轻松实现单击文本框弹出选择日期
首先创建个文本框
<input id="txFDate" name="txFDate" type="text" value="" onfocus="setday(this)" runat="server"   />


可以看到文本框有个onfocus触发事件,现在就贴上这个事件的代码(代码比较长,但是只需要复制所有代码把他写进一个js,然后在调用这个JS即可):


calendar.js


// 主调用函数是 setday(this,[object])和setday(this),[object]是控件输出的控件名,举两个例子:
// 一、<input name=txt><input type=button value=setday onclick="setday(this,document.all.txt)">
// 二、<input onfocus="setday(this)">
//function setaa()
//{
//alert('1111');
//}
